FIX: Asus Computer Boots Into Aptio Setup Utility Instead of Booting Into its OS

The Aptio Setup Utility is kind of a variant of the BIOS setup utility, although the Aptio Setup Utility usually only comes with Asus desktops and laptops. Quite a lot of Asus computer users have faced and continue to face an issue where their computer continuously boots into the Aptio Setup Utility instead of booting into its Operating Systems. An Asus computer usually does so because it does not detect an Operating System that it can boot to or doesn’t have an HDD/SSD connected to it entirely.

However, if you are certain your Asus computer has an HDD/SSD with a viable installation of an Operating System connected to it but are still experiencing this issue, there can only be one of two explanations for it – the connection between your computer and its HDD/SSD has come loose, resulting in your computer not being able to detect it, or your computer simply can’t detect its HDD/SSD and recognize it as such. If the latter is the case, your computer might not be detecting the HDD/SSD because most Asus computers are configured to not recognize any HDDs/SSDs other than the ones they come with, and your computer, for some reason, thinks that the HDD/SSD in question is not the one it came with.

This issue is especially common in Asus laptops. Thankfully, though, this problem is not unfixable, and the following are the two most effective solutions for this problem:

Solution 1: Make sure that your computer’s HDD/SSD is correctly connected

The most obvious cause of this issue in your case would most likely be that the connected between your computer and its HDD/SSD has somehow been rocked loose, rendering your computer unable to detect its HDD/SSD. If this is, indeed, the cause of this issue for you, all you need to do is fasten the connection between your computer and its HDD/SSD. In order to do so, you need to:

1. Open your computer up to gain access to its HDD/SSD. If your computer’s a desktop, open its casing. If your computer’s a laptop, unscrew and remove its bottom.
2. Locate and unplug the drive’s connection from your computer’s motherboard.
3. Clean out both the drive’s connection and its socket it your computer’s motherboard.
4. Plug the drive’s connection back into its socket on your computer’s motherboard, making sure to seat it correctly and firmly.
5. Close your computer up.

Boot your computer up and check to see if the issue still persists.

Solution 2: Allow your computer to detect foreign HDDs and SSDs

If your computer’s HDD/SSD is connected to it as best it can be, you might be suffering from this issue because your computer is set to not recognize foreign HDDs and SSDs the HDD/SSD you are trying to use is either not the one your computer came with or your computer simply believes that to be the case. If this is the root of this issue for you, this solution might work quite well for you. To allow your Asus computer to detect foreign HDDs and SSD and recognize them as such, you need to:

1. Boot your computer up and wait for it to boot into the Aptio Setup Utility.
2. Once in the Aptio Setup Utility, navigate to the Security
3. Expand the Secure Boot menu section and disable Secure Boot.
4. Navigate to the Save & Exit tab, save your changes, exit the Aptio Setup Utility, restart your computer and wait for it to boot into the utility once again.
5. Navigate to the Boot
6. Disable Secure Boot and Fast Boot
7. Enable CSM (Compatibility Support Module).
8. Navigate to the Save & Exit tab, save your changes, exit

the Aptio Setup Utility and restart your computer. When your computer boots up, it should boot straight into its Operating System and not into the Aptio Setup Utility.
